riment when the spinner was spun 90 times:
Result of Spin Black White
Number of Spins 72 18


Based on the data, which of the following best describes the experimental probability of the arrow landing on a black or white section of the spinner?
The spinner is equally likely to land on black or white.
The spinner is 4 times more likely to land on white.

Answer:

The spinner is 4 times more likely to land on black.

Step-by-step explanation:

There were 72 black spins compared to 18 white spins.  This means there were 4 times more black spins than white spins; this means the spinner is not equally likely to land on either color.

Part A: Abe rented a bike at $36 for 5 days. If he rents the same bike for 8 days, he has to pay a total rent of $48.
lawyer [7]
(5,36)(8,48)
slope = (48 - 36) / (8 - 5) = 12/3 = 4

y = mx + b
slope(m) = 4
(5,36)...x = 5 and y = 36
now sub and find b
36 = 4(5) + b
36 = 20 + b
36 - 20 = b
16 = b

equation is : y = 4x + 16.....in standard form : 4x - y = -16 <==
=======================
function notation : f(x) = 4x + 16
=======================
x axis will be ur hrs....I would label them at intervals of 1
y axis will be total cost of renting the bike......as far as the intervals...not sure how to label them.....sorry....I wanna say intervals of 2...but am not sure

y = 4x + 16
slope = 4
y int = (0,16)
x int = (-4,0)

so start at (-4,0)....and since ur slope is 4, go up 4 and to the right 1...keep doing this and u will cross the y axis at (0,16)

Bob the archaeologist is in the desert, 10 km from a long, straight road and 45 km from base camp. The base camp is also 10 km f
Arturiano [62]
Answer: Bob can make it to base camp in about 1.6 hours.

If I am understanding the problem correct, Bob must drive 10 km to get to the road through the desert. Then, 45 km on the road. And finally, another 10 km off the road to get to the base camp.

We end to find the time for each section of the trip.

Start with the formula: d = rt or t = d/r

Now, we can divide to determine the amount of time for each section.

1) 10 / 30 = 0.333 hours
2) 45/50 = 0.9 hours
3) 10/30 = 0.333 hours

Add up all the times, and you get about 1.6 hours.
